HEEL TRIMMING AND BQREASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 293,628, dated February 19, 1884. Application filed August 8, use. (No model.) i

To col? whom it may concern:

Be 1t known that I, ULDERIO D. BYRON, of

' Chicago, in the county of Cook and State of Illinois, haveinvented new and usefullmprovements in Heel Trimming and Breasting Machines, of which the following-is a specifi- Y embodying my improvements, the supporting frame or standard being shown in section.

Fig. 2 is a side view of the same, looking in the direction of dart Y, Fig. 1. Fig. 3 is an en larged perspective viewiof the cutter-head guards, guides, and supporting-arm. Fig. 4 is an enlarged perspective view of a portion of the mechanism removed; Fig. 5, Sheet 2, a side elevation of Fig. 3; Fig. 6, a plan or top view of the head of the machine and jack.

The object of the present invention is to provide means for gouging, beveling, and breasting boot and shoe heels without removing the heel from the'jack.

The nature of the present invention consists, first, in novel mechanism whereby the breasting-knife and cutter-head act independent of each other, but both are driven by the same drive-gear; second, the novel means for connecting and hanging the jack-lever,whereby the jack can be vertically rocked and have reciprocating motions, the means consisting of l a reciprocating rock-sleeve and bearings, which differ essentially from the mechanism employed in ordinaryheel trimming machines, in that the shaft is hung centrally by means of the rock-sleeve to have an oscillating movement and the sleeve to have a lateral reciprocating movement on its axis, instead bf moving the whole frame, as is done in some other machines to attain this latter movement; third, the means whereby. the breasting knife is moved only when in aotualuse by the construction to attain this end theknife is always in position to perform its work, and the friction of the machinery to give to the knife a lost motion is obviated, and another advantage is, there is no danger to the operator or the jack while the heel is being trimmed by the cutter-head; fourth, in other detail mechanism for giving effectiveness to the machine in adjusting and guiding the parts properly to perform the trimming work to be done, as hereinafter more fully described and shown.

A is the supporting frame or standard. B is the drive-shaft, which is driven by ordinary driving-gear, G G O, and supports and revolves the cutter-head S. The standards A A and 14 14 are made of T-shaped iron; but any convenient form will answer the purpose. An

arm, E, on standard A is provided at its outer end with trunnions 1 1, which support arms 2 2, attached to a sleeve, 3, and have a reciprocating movement in the trunnions. The jack-lever D is attached tothe sleeve 3 at its central part, andto connecting-rod G by clip 26. By this construction the jack-lever can be rocked vertically on the arms 2 2, and reciprocated laterally, as stated, by the sleeve movement. The lever Q is the means for operating the jack in its reciprocating motion, and is pivoted to the arm E at 19. The heel, R, to be trimmed is placed between the forks F F of the jack, the face of the heel, to which the pattern a is attached, against pin 11, and

the upper side against clamp-rod 12. 'A segmental internal cog-rack, 5 is rigidly attached to arm F by pin 8. Lever 7 is hung to gear 6 by pins 8 9. The holes through which these pins pass are larger than the pins, to allow the lever to have a vertical rocking movement.

The heel B being placed in position, as stated,

thelever 7 is to be first pressed down to release the end 27 from rack 5, and then forced in direction of dart Z, Fig. 3. 1 The cog-gear-G engages cog-gear c on red 12, and the latter is by this means brought firmly against the upper side of the heel, and the lever 7 is then locked to hold the gear firmly by tipping it so that its end 27 will drop into rack 5. The clamping-rod has ordinary bearings, d, at the outer end of arm F, as shown at Figs. t'and 5, and consists oftwo collars or sleeves, in which the rod 12 is operated. This rod12 is of uniform diameterwhere it passes through the sleeves, the cogs or teeth 0 being formed by siinplygrooving the rod. This is that it ings d to operate as above stated. The connecting-rod G, attached to the end of the jacklever D and to weighted foot-lever I, holds the j ac-k to the outter-head knives, and when the heel is trimmed the jack is brought down by means of the lever I, so that the heel will be opposite hrcasting-knife H. The lever K is raised by means of lever J and connecting-rod J, so that its head 16 will engage pin 13 on wheel L. This wheel L, supported by standards 14 14, is driven by a worm-gear, M, on shaft 13. Lever K is pivoted to knife H at 10, and so, when the pin 13 strikes the lever-head l6, knife H is driven forward in the grooved frame N and cuts off the front of the heel. During this operation the outer end of rod 12 is in contact with an ordinary resisting-bloek, m, which is separate from the machine, but is a permanent fixture relative thereto. The knife is brought back to its former position by coil-spring O. The pin 13, as shown in Fig. 1, is in the position on wheel L it would be when heels of medium depths are to be out. To cut higher heels the pin 13 is moved in the slot 18 nearer to the periphery of wheel L, and to out lower heels the pin is moved toward the center of the wheel. A guard, 20, of ordinary construction, protects the upper from injury by the knives S, and is sharpened at its edge, so as to pass between the heel andupper without much friction. This guard has a vertical adjustment to conform with various depths of knives that may be used, and its operation is as follows: Through plate r on slotted arm P is a screw, which is provided with collars t t, bearing againstboth the upper and under sides of the plate. Thelower end of thescrew engages the threaded sleeve 0, attached to guard 20, so that by turning screw f in plate 4 the guard will be lowered or raised, as desired, the slot at allowing it to move vertically on shaft B. Plate 1' is slotted at m m, so that it may be adjusted horizontally on arm I? and held in place by set-screws l lwhen in the desired position. This is so that the guard can be brought to the ends of cutter-heads of various widths. Pattern-guide 28 is slotted, and has the same vertieal adjustment as guard 20.

Vhen trimming a heel which has a varying depth, to bring every part to be trimmed under the knives, it is necessary to push the guide back from the end of the cutter-head. To allow this movement, the sleeve 0, Fig. 4, at its lower part is provided with a grooved bearing, 71, on which the guide reciprocates. The coil-spring a, with loose collar 2) on shaft B, steadies the guide and brings it back to its former position when the greater depth of the heel has been trimmed. The cutter-head knives are of steel and in the form shown, so that they can be conveniently sharpened. The knife-edges are provided with projection s to bevel the edge of the heel next to the upper. I do not, however, claim the construction of the cutter-head in this application, but confine myself to the use of it as a part of a combination only.

Having thus described my invention, I claim as new- 1. In machines for trimming and breast-ing boot and shoe heels where the breastingknife and the cut-ter'head operate at different times on the heel, the intermediate gear-shaft, B, of

the cutter-head, and the intermediate gearand 3 by mechanism to have vertical rocking and horizontal reciprocating motions, as described and shown.

3. The wheel L, provided with pin 13, dison the lever J J K 16, in combination with wormgear M and breasting-knife H, as a means for breasting a heel at the proper time, while there is a continuous movement of the driving-gear.

4. The guard 20, combined with the plate a, slotted at m m, slotted arm I and set-screws Z Z, for adjusting the guard to different lengths of cutter-heads.

5. The pattern-guide 23, hung to a grooved support, h, in combination with spring 0, to allow heels of varying depths at all parts to be brought to the knives.
